1.1Preparing for a Bicycle Tour
The experiment requires four people:
a jumper (to do jumping jacks)
a tmer (to keep track of the time)
a counter (to count jumping jacks)
a recorder (to write down the nmberof jumping jacks)
As a group, decide who will do each task.
prepare a table for recording the total number of jumping jacks after every
10seconds, p to a total timeof 2 minutes (120 seconds).

Problem 1.1 Follow Up 1.
How did your jumping jack rate (the number of jumping jacks per second) change as time passed? How is this shown in your table?
The rate of jumping jacks was consistent as time passed. The rate was around one and 1/10 of a jumping jack every second for 70% of the time. The other 30% of the time the rate went to9During the last ten seconds the rate went down to one jumping jack every second.This proves that the rate changed over time. 2. What might this pattern suggest about how bike - riding speed would change over a day's time on the bicycle tour?
This pattern might suggest that during a day of bike – riding that the rider would go faster at the beginning of the day when they started then at the end they would go slow.
